The Contest (1992)
After George's mother catches him alone in a somewhat embarrassing situation, Jerry, George, Elaine and Kramer stage a contest to see who can last the longest without any sexual gratification. Temptation quickly sets in for everyone. Kramer is the first to fall after ogling the woman across the street who walks around her apartment naked. George is next after he visits his mother in hospital and her roommate gets a sponge bath across from the curtain separating them. Elaine signs up for a fitness class where none other than JFK Jr. is enrolled. Her fantasizing does the rest. Finally, Jerry's new girlfriend Marla decides it's time to lose her virginity but Jerry has to explain the contest.
